GUILLERMO MIGHELENA, OF NEW YORK, N. Y.

IMPROVEMENT IN BREECH-LOADING FIRE-ARMS.

Specification forming part of Letters Patent No. 148,571, dated March 17, 1874; application filed September 18, 1873.

To all whom it may concern:

Be it known that I, GUILLERMO MICHEL- ENA, of the city, county, and State of New York, have invented a new and useful Improvement in Breech-Loading FireArms and I do hereby declare that the following is a full, clear, and exact description thereof, refercnce being had to the accompanying drawings, making part of this specification, in which- Figure l is a vertical longitudinal section of a gun having my improvement applied thereto, the breech being closed. Fig. 2 represents a corresponding section with the breech-block open to allow of the introduction of a cartridge into the chamber of the gun. Fig. 3 is also a corresponding section, showing the various parts composing the breech mechanism and lock in still different positions-the breech of the gun closed by the breech-block, and the hammer in position to move forward and explode the cartridge.

My invention consists in the construction and arrangement of the breech mechanism and lock to a gun so that by the single movement of pulling the trigger the breech-block must first close to its seat, and, by a continuous movement of the trigger backward, will subsequently release the hammer to explode the cartridge.

Like letters designate corresponding parts in all of the figures.

The barrel A, stock B, breech-block O, hammer and lock block E, and firing-pin F are the same in general form, and well known to those skilled in the art, as the Remington breechloader, and requiring no further description in this application.

In order that the breech-block (1 shall close and the hammer be released to explode the cartridge by a single movement of the trigger, the front end or toe a of the trigger b is elongated, and extends sufficiently forward to take into a notch, 0, formed in the lower edge of the breech-block C, as shown in the several figures. Beneath this toe or elongation ais placed a spring, (7, bearing against its lower surface, which serves to retain the toe a in g in the lower side of the hammer E. The

sear f is held against the lower edge of the hammer by a sear-spring, i, secured to the stock B in the usual manner;

In Fig. 2 the hammer E is represented as drawn back, and the breech-block G thrown down in position to allow of the insertion of a cartridge into the chamber of the gun. In these positions the toe a of the trigger b rests in the notch c of the breech-block, and the sear f rests in the notch g of the hammer, in which positions, by simply pressing the trigger, the toe to thereof will release the breechblock (3, which is thrown upward and forward by means of the spring w, closing the breech of the gun, and, by a continuous movement, the lower side of the trigger is brought in contact with a pin, 1, projecting from thesear f, which releases the hammer to explode the cartridge by means of the mainspring G and firing-pin F. Thus, when the breechblock is released and thrown into position against the breech of the gun through the action of the spring w, and the hammer still held back by means of the sear f, the parts will assume the relative positions, as shown in Fig. 3, the breech-block against the chamber of the gun closing it, and the hammer in readiness to move forward, lock the breechblock, and explode the cartridge through the medium of the firing-pin F.

When desired to close the breech-block, and not explode the cartridge, it may be readily accomplished by placing the thumb upon the hammer and arresting its forward movement, releasing at the same time the breech-block through the trigger, which will immediately close to its seat, after which the hammer may be lowered to half-cock, or to the breech C and release the hammer E, to

rest upon the firing-pin F, if preferred. explode the cartridge by the one movement Having thus fully described my impror'eof the trigger, substantially as herein set ment in breech-loading fire-arms, what I claim forth.

therein as new, and desire to secure by Lettars Patent, GUILLERMO MIGIIELENA.

The combination of the breech-block C, Witnesses: spring w, hammer E, trigger b, and scarf, I MANUEL MUfiOZ,

when so constructed and arranged as to close S. MIOHELENA.
